Screen Refresh is slow in Develop - OpenCL CA On/Off and Renderer GTX1050 or Intel HD630 or WARP Block

Seems to be a regression in the Develop Persona as I am getting Blocks on the screen as in the screenshot below:

 

Note this does not happen in the Beta 1.10.0.1127 with the GTX1050 as the renderer.

Same thing here with an integrated Intel HD620. Affinity Photo 1.10 final is much slower in rendering and updating with OpenCL enabled than it was in 1.9.

Disabling OpenCL made it quicker for me :(.

 

My other machine with a GTX1060 (desktop) seems to run fine with it enabled though, although I have the feeling tha tit also runs a bit slower there than it did before. It's at least not slow enough to disable OpenCL.

 

On a laptop like yours with two GPUs, maybe you need to flag in Windows that the Affinity Photo app is supposed to use the 'performance' GPU. Or in the Nvidia panel, you can say that the application should run on the dedicated GPU. Maybe you are using your HD630 behind the scenes and running into the same issues as I  (and others) have with an Intel HD6xx and Affinity Photo 1.10.

Thanks, it is already flagged in the Graphics settings and set to High performance (GTX1050).

Disabling OpenCL certainly helps but then there is a flicker moving between Personas.

If you're getting this with WARP and OpenCL off and on, it might be the image - does this happen if you enter Develop Persona with a JPEG?

Same over here, Photo persona, (1 sharpen layer)  Nvidia GTX1060, Disabling OpenCL helps

Hi Chris, In the latest version this blocking is there but only with OpenCL Acceleration turned on and ONLY with uncompressed RAW from Sony. Others such as CR2, CR3 and RAF seem to be OK now even with OpenCL Acceleration on.

Note: Screen refresh still flickers noticeably with OpenCL off.

I've seen the flickering happen when a selection is active. It's much worse that on macOS where it's barely visible. The flickering will be from redrawing the canvas when switching personas. I imagine you might see it from zooming too?

I'll grab an uncompressed Sony raw file and see if I can repo - it may be worth attaching one too if you have one to share.

Ok, shall do in 8 hours or so.

Thanks AiDon, 

I've grabbed a few from rawsamples.ch but they seem fine!

[AiDon]

Try this one Chris, under Windows OpenCL also selects both GPUs for hardware acceleration.

Thanks AiDon. I got it straight away with this file. I'll get this logged
